I beg to disagree: is 02020202 a number or a date? It is better to
flag an error instead of trying to read minds. If some data is meant
to be a date, it is a good idea to have this expressed somewhere,
either in a type declaration in a schema, or by using explicit
conversion functions in the expression.
Explicit type conversions might also be good for optimizations.
